It is something that can work alongside this forum to solve problems with Arduino's. It in no way replaces a forum, but instead creates a new platform for objective oriented questions and answers with minimum noise. If you are interested, you can follow and support the proposal. The more the merrier

Bah. Dilution of mindshare. I already regularly read here and at Adafruit, and feel like I should read Sparkfun; there's a limit to how many websites I'm willing to visit on a regular basis, to cover one subject...

FYI: This proposal was already made last year, and then after reaching completion, it was closed down by Stackexchange moderators/staff, because it would dilute users away from the Electronics Stackexchange, which already has an active community answering Arduino-related questions.

Yes. I am aware. Things are being actively discussed. We have had some communication with SE employees as well. They will take a call on this proposal only when it reaches the next phase of the process. However, it has been observed that this proposal is different, wider and we are targeting a much wider audience than before.

Dilution of content is indeed an issue for Arduino community (although less so than many other tech fields).

That said, I think this Stackexchange proposal for an Arduino site will definitely be useful in certain aspects -- Stackexchange emphasizes content creation and curation in a way that is future-reader-friendly. So this will result in more signal-to-noise ratio, community-voted answers, and less redundancy, but also quicker access for any information an Arduino user might be interested in.
